How does a torque sensor work on an electric bike?

A torque sensor on an electric bike measures the force or pressure applied to the pedals by the rider. It then sends this information to the electric motor, which adjusts the level of assistance provided based on the rider's input. This allows for a more natural and intuitive riding experience, as the motor responds to the rider's effort in real-time. The torque sensor is typically located near the bottom bracket, where the pedals attach to the bike frame. By accurately detecting the rider's pedal force, the torque sensor ensures that the motor provides the right amount of power, whether it's for smooth acceleration or climbing steep hills.
